Fort Irwin is accessible via Interstate Highways 40 and 15 and
State Highways 58 and 247. If possible, you should plan your arrival during
daylight hours especially if you have reservations at the Landmark Inn on post.
The desert can be very dark at night and roads are not well lit. There are no
gas stations between Barstow and Fort Irwin.
Arriving via highway 58:
Recently completed construction (which maps do not reflect) now feeds Highway 58
into I-15. Take I-15 North towards Barstow/Las Vegas.
For those
proceeding directly to Fort Irwin, exit I-15 on Fort Irwin Road. Coming from the
east (I-15 South), the turn-off is prior to arriving in Barstow. Coming from the
west (I-15 North), the turn-off is approximately 6 miles past Barstow. After
turning, the mileage marker will read 31 miles to Fort Irwin.
